Background: Development of Left ventricular hypertrophy (LVH) in hemodialysis (HD) patients is reported in different clinical studies. The mechanisms responsible for LVH in these patients are complex and multi-factorial. Experimental studies have shown that Nitric oxide (NO) is a possible anti-hypertrophic molecule. The aim of this study was to assess(More)
Charge-transfer (CT) complexes formed from the reactions of two N,N'-bis-alkyl derivatives of 1,4,6,8-naphthalenediimide such as N,N'-bis[2-hydroxyethyl)]-1,4,6,8-naphthalenediimide (BHENDI) and N,N'-bis-[2-N,N-dimethylaminoethyl)]-1,4,6,8-naphthalenediimide (BDMAENDI) with chloranilic acid (CLA) and piciric acid (PA) as pi-acceptors, have been studied(More)
We describe a method of cup and cone arthrodesis using Coughlin concave and convex reamers, which we have used in a series of 22 hand joints in 19 patients. These reamers, originally designed for use in the foot, can be used in the hand to give very accurate preparation of bone surfaces. This results in maximum bone contact and the ability to fuse the joint(More)
The first cases of systemic lupus erythematosus (SLE) with effects on the nervous system were reported more than 100 years ago. Cerebellar involvement and obstructive hydrocephalus are rarely encountered in patients with SLE. We report two patients with SLE who developed cerebellar ataxia. The first patient presented with significant headache at time of SLE(More)
